The panel it will be noted is of smaller .dimensions Ehen the inside dimensions of the or and by ineens of the arch brackets is posed apart from the bottom of the box or collines so that :imple 'wiring space is permitted between the bottoni of the penellooerd end the bottoni of the TooX, whereby cli-e leerling-in Wires may be brought ino ille box from any Side, ample room being!

The branch circuit Conductors or Wires are brought in through suitable conduits suoli es one of which is located opposite each pli-i1 of branch circuit fuse receptacles, and are conneetecl to the bindingposts 16 of the {.lilferent branch Circuit units. After all electrical connections are made a. cover-plate 38, preferably formed of sheet stoel and snugly fitting {v -lie bor: or cabinetis placed in positionu This cover-plate has suitable openings formed therein coinciding with the dilferene fuse recepincles, through which the fuse receptacles are adapted to pass, and the Wells of these openings snugly fit around these receptacles so that the panel-boord, and particularly the exposed conductor parte of the panel-board, are completely enclosed :md protested. In other Words, the coverplate 38 forms :i flood front shield to prevent any occidental cantaor with the live parts of lino naar l. This rover-plaie 38 is supported upon e. pair'of brackets one at euch end, the legs 4() of which are provided with intnrnecl lugs .41' to which. the shield is secured.

Two of these .diagonally-opposed nptnrnefl lugs 4l, in the drawings the upper rig-ht and lower left' one7 :1re equipped with threaded boite 42 which engage the tapped holes 43 in each of seid lugs. These bolts are inserted from the under side of the lugs and' time project upwardly from the upper 'fece of the lugs. Each o1- tlie bolts is trans ilersely perforated, the perforetions serving to receive e wire which functions :is n sealing Ineens when the eovenplote 38 has been put in place.

The brackets 39 which snpiort the 'coverplae 38 rest upon the bmokets 35 which support the panel-board, being interposed between the bottom of the panel und the brzielet Snitnlole screws suoli as 43', poss through the panel-boarcl base, through lie brackets 39, and engage in the bracket 35, thereby securing all. these parts rigidly conci-board and for mounting said dead shield, seid brackets and panel-board assembled' es a physical entity,` the for mounting said panelboerd prog e. wiring space between the bottom f of seid panebboard and the top face the bottom of seid enclosing structure; eno :.neene whereby seid entity Ycan be iclly end eesily mounted in and removed lione. seid-penel-boza enclosure;
